This volume investigates identity traits in academic discourse. Its main purpose is to better understand how and to what extent language forms and functions are adapting to the globalisation of academic discourse. Key factors of verbal behaviour such as the affiliation of actors to one or more cultures have been found to interact, producing transversal identities that are independent of local traits, with a tendency to merge and hybridise in an intercultural sense. The volume consists of three main parts: The first deals with identity traits across languages and cultures, as the use of a given language affects the writing of a scholar, especially when it is not his/her native language. The second comprises investigations of identity features characterising specific disciplinary communities or marking a differentiation from other branches of knowledge. The third part of the volume deals with identity aspects emerging from genre and gender variation.
